DMS-100 Protocol Version 1 Line Additional Parameters
The Northern Telecom DMS-100 telephone switch supports a
proprietary ISDN D-channel call control protocol called Pvc1
which is based on CCITT recommendations. The ISU 2x64 con-
figured for switch-type DMS-100 is functional on lines providing
this protocol on DMS-100 switches with software version BCS-32
or later. The ISU 2x64 supports the following configurations on
DMS-100 lines:
• Multipoint with one phone number (1B+D service)
• Multipoint with two phone numbers (for 2B+D service)
The requirements for the DMS-100 multipoint line are defined in
the sections Local Interface, Local Service, and in Table F-B, all in
this appendix. The line should have two service profiles with the
following parameters to support BONDING.
